<h2>DESCRIPTION</h2>

<em>t.info</em> reports information about any dataset that is
registered in the temporal database in human readable or shell script
style. Datasets are raster, 3D raster and vector maps as well as their
corresponding space time datasets (STRDS, STR3DS and STVDS). This
module reports the information that are stored in the temporal
database. These are basic information (id, name, mapset, creator,
creation time, temporal type), the temporal and spatial extent and
dataset type specific metadata. The user has to utilize <em>r.info</em>,
<em>r3.info</em>, <em>v.info</em> to report detailed information about
raster, 3D raster and vector maps, since not all map specific
information and metadata are stored in the temporal database.
<p>
In addition, information about the chosen temporal database backend
can be reported.

<h2>NOTES</h2>

Temporal databases stored in other mapsets can be used as long as they
are in the user's current mapset search path (managed with
<a href="g.mapsets.html">g.mapsets</a>).

The "granularity" is the smallest gap size between the found time instances, i.e.
it the greatest common divisor between all gaps in the time series.
